Upon completion, participants should be able to:
- Outline the diagnostic potential of various GD3 biomarkers currently under investigation
- Evaluate recent clinical data on the treatment of GD3
This activity is intended for hematologist/oncologists; pediatricians; medical, translational, molecular, and research geneticists; and other healthcare professionals with an interest in the clinical management of patients with lysosomal disorders.
Statement of Need
GD3 is a subtype of one of the most common lysosomal disorders, GD. Like all subtypes of GD, GD3 is caused by various mutations to the GBA1 gene, which encodes glucocerebrosidase. GD3, also known as chronic neuronopathic GD, is associated with a wide spectrum of visceral and neurologic manifestations. The GD3 phenotype is further divided into 3 subgroups based on the severity of visceral symptoms and cardiac involvement. Determining the genotype variations in GD3 that lead to different phenotypes and disease progression is an area of active research.
Diagnosing GD3 can be challenging as the divisions between the different types of GD are still being identified. Indeed, the manifestations of GD can be described as a phenotypic continuum. Thus, it has become increasingly evident that biomarkers might hold the key to differentiating diagnosis; several biomarkers are under investigation.
Currently, no treatments are specifically approved for GD3; however, mounting evidence suggests that enzyme replacement therapy (ERT) in combination with substrate-reduction therapy (SRT) might be an effective treatment. New therapies specifically for patients with GD3 are under investigation.
